Not a bad opener, just pull uke's upper body down and bring your tori's leg up and into position for a kick, then lower your arm and build up momentum for the kick, aim up the kick and extend the knee. Preferably kick with your left leg because it will have more flow than kicking with the same leg twice.
I would recommend you aim for a kick with at least 2 dismemberments, the whole setup would be a bit much for just a decap or any other single dm hit.
Also while doing the kick attempt to maintain contact with the ground and stay upright.
Will be interested to see what you come up with.
have fun
